temperature Probes l Flexible Teflon microprobes are used for implantation in tissue, in spectrophotometer cuvettes, rectally in neonatal mice, in water baths, PCR thermal cyclers, etc. l Animal rectal temperatures during surgical procedures and pyrogen testing. l Skin temperature measurement during exercise physiology studies. When precise temperature measurements are required, WPI can provide you with a very accurate monitor and thermocouple microprobes. WPI monitors have both resolution and accuracy of 0.1°C in the 0-50°C range and are traceable to NIST standards, whereas, other competitive electronic thermometers have Probe Type Size Style Time Constant Isolated an accuracy that is usually to 0.5°C or worse. Furthermore, all our type T clinical probes are guaranteed accurate to 0.1°C, due to our stringent wire standards. These are five times more accurate than competitive probes made with regular “Special Limits” wire. AN I MAL S U RGERY & S U PPORT Max. Temp.

Needle (supplied). Rather fragile. Teflon coated. As IT-18 sensor except bead exposed. Combines ultrafast reponse of IT-23 with sheath strength of IT-18. Rectal probe for rats typically for fast intermittent measurements. Smooth ball tip (0.125-in. dia.) with 1" long (0.59-in. dia) stainless steel shaft. Rectal probe for mice similar to RET-2 except tip diam. 0.063-in. and shaft 3/4-in. long (0.028-in. diam.) “Workhorse” probe for liquids, gases, semi-solids. Plastic handle with straight stainless steel shaft. Not good for surface temperatures. Like HT-1 except shaft length is 9-in. Plastic handle with welded stainless steel, immersible shaft used for surface temperatures of solids, liquids, gases and semisolids. Tip is 0.02-in. diam., at right angle to probe to facilitate surface measurement.
